Hey folks, I have to tell you, TRP replaced my Hy/RD original calipers with new ones and the new ones are incredible. Slick as full hydrauilic but simpler, liner progression of brake force, smooth as glass feel, powerful, no fade, perfect self adjusting (finally), simply awesome. I am running Avid HSE 160 rotors front and back. I do not hate to put on the brakes anymore, the stopping feel is almost as great as the acceleration feel. The control is incredible. There should be no other brakes out there. And to think I used to think BB7s were great. These Hy/Rds have to be tried to appreciate them. If you try them, plan to bring the cash to just go ahead and buy them because you will like them so much.
I've been pretty happy with my first gen Hy/Rd brakes. You have me curious about what is different with the new ones and how you had them replaced.
Out of curiosity I have even tried to overheat them by riding just one brake on a long decent trying to hit the fade point. No dice. I lost my nerve before the calipers started to fade.
My only worry is that now with auto adjust working, I will not know when the pads are worn to the point where they must be replaced. I will have to remember to manually keep checking.
These ara an absolute joy to ride. I have let a few friends try them and they all agree!
Yes sorry if there was confusion. I have the hy/rds on a single bike. I have used bb7 calipers on both single and tandem. I can tell you that comparing bb7 vs hy/rd on a single bike shows an incredible improvement and I would love to have them on a tandem. These out perform bb7s on a single bike so I would expect they would outperform on a tandem too. I am also using without compression less cable housings too so I would expect with compression less to be better still.
Great technical info..........but does anyone have any real or actual braking experience with this TPR on their Tandem......and how does it compare to the Avid BB7?
My BB7's fronts squeal constantly......obnoxiously!.........only get about 20-30 miles without squeal after I clean rotors and pads with alcohol.......considering the TPR as a alternative solution......can not go to a cabled brake system without changing my Co-motion carbon fork on the Calfee.
Footnote: Rear disc brake hardly ever squeals........
Yes, many of us do have experience running T-R-P calipers on our tandems. It may be a bit confusing exactly what works and doesn't, because unfortunately this SPYPE thread is constantly highjacked by HY/RD users who can't seem to create their own thread.
Regardless of caliper type, most squealing can be resolved by choosing a different rotor because the resonance frequency will change. I have yet to have any squealing from the Shimano ICE rotors with either the BB7 or the TRP Spyre.
TRP has their own adapter bracket which is a different height than the Avid (which adds their CPS washers), but I've found the 203mm TRP adapter is not as thick and does not align the caliper perfectly centered horizontally... needing either/both filing or thin washers to place the caliiper centered over the rotor.
When properly aligned/installed, the Spyre does seem to have great stopping power and does not have plastic parts as with the BB7. We are currently using the 203mm Shimano Saint RT99 Centerlock rotor on the rear braking and it is very smooth.
I had the same problem with the BB7 squealing. No such problem with the TRP Spyre using the same Avid rotor. Works great on the hills of the Adirondacks. At the moment, I am trying to fit a set of Hope floating rotors with the TRP. My problem with this set up is in the vertical direction rather than 2cicle's horizontal (the brake pads are scrapping the floating bolts). A couple of washers should do the job.
If reusing the Avid, then you'll need to add some ~3mm worth of spacers to move the caliper higher up.
FYI, not all Hope floating rotor rivets are located the same. The Hope rotor I got has more braking surface (top to bottom) than some of the other models, and the rivets are lower - away from the pads so no problem with clearance. As seen here: http://www.amazon.com/gp/product/B00...?ie=UTF8&psc=1. I think it is far superior to one piece steel rotors.
I'll maybe use it again in the future via a DT CenterLock adapter (to fit on our new rear hub), but right now happy with the ICE rotor.
My BB7's fronts squeal constantly......obnoxiously!........]
We also got tired of the noise, especially the front, not sure why front is worse. Anyway, my fix was organic pads. They are quiet, but, downside you should be aware of: they don't handle heat as well nor water. Thay also wear faster
Ok, so my week #2 update on the front pads squealing…had cleaned them with Windex…2 weeks ago…..rotor and pads….first 20-30 miles had virtually no squeals….then started up again but intermittently….based on modulation or pressure application to the grips…..after another weekend of riding and about 75 miles…..have a mixed bag of no squealing to slight and intermittent squealing but nothing like it was before….
Testing it this weekend on a metric ride in Ventura with some downhills of 8% grades and will report back….probably will transition to new pads and go from there.
Front disc is a Avid BB7 silver with about 600 miles on a 2014 Calfee Tetra Tandem
Just a little update on my setup:
The 180 mm Hope floating rotor will not work correctly with the TRP Spyre. The floating rivets are too close to the braking surface and will scrape on the Spyre's caliper/pads. I played around with the different washers and mounts and did get it to fit. But, ultimately, I was not comfortable with the odd angle and slightly reduced braking surface the new setup entails. So these rotors are going back.
